Maxwell34 the 6% is Pennsylvania state sale tax.
Pennsylvania law requires the payment of use tax by any person who purchases taxable goods or services delivered into or used in Pennsylvania if sales tax is not collected by the vendor. Use tax is the counterpart of the state and local sales taxes.

After the latest Supreme Court ruling regarding "Internet Sales Tax" in June 2018, a number of states tax authorities are trying to get their hand in the cookie jar ahead of their congress to ratifying or amending state law.

You can try to appeal the ruling from the state tax office by using the "Manufacturing and Processing Equipment" clause dealing with items and services would remain exempt from Pennsylvania's sales tax law under Gov. Tom Wolf's 2015 budget.

Note: We had to appeal a similar tax order in Kentucky and won.

Interesting Idea.  I just pledged for a set of 3 Titanium Coin Armors.
If it works out I will be buying more for the kids and clients.

Thank You and Good Luck with your new adventure.

I hate to burst your bubble, but the SP-50 is a "Mythical Unicorn" and was designed but never produced for sale. 

Please see Forum Post https://bitcointalk.org/index.php?topic=521520.0 written by the official "Spondoolies-Tech" account ( https://bitcointalk.org/index.php?action=profile;u=295386).


Good Luck with your mining. Have fun and be safe.

Have you looked at Grey Matter Cases ( https://www.miningrigs.net/product-category/server-cases/ ).

They have a all in 1 Rack mount shelf in a 6U format designed to secure 3 Bitmain's Antminer S7/S9 & 3 power supplies.  Hash power could be 3x 4.7/13.5 (totaling 14.1 / 40.5 ) TH/s respectively, depending how you configure them.

Hope this helps.

MarkAz,

Your 5th generation open rig with Sidehack's wrapped cables and molex breakout boards looks very clean and might be something we would be interested in.  Are you selling these rigs (Complete or just shells) or selling the plans with a parts list?



Thank you for your time in advance,

 /s TuffToad

Happy Birthday Jonny!

Thank You philipma1957 / Judypug1956,

I can now make a rough calculation what kind of bill to expect when new miners arrive (USA, Midwest).

Thank you SP.

For those not familiar with the word "EDGARizer" it refers to Electronic Data Gathering, Analysis and Retrieval a online public accessible database set up by the US SEC (United States Securities Exchange Commission) set up by the The Office of Compliance Inspections and Examinations ("OCIE") to protect investors & future investors through administering the SEC's nationwide examination and inspection that all parties have equal access to information provided by any party related to a "Public Companies" activity.

What is EDGAR?  EDGAR (Electronic Data Gathering, Analysis, and Retrieval) is an online public database from the U.S. Securities and Exchange Commission (SEC). EDGAR performs automated collection, validation, indexing, acceptance, and forwarding of submissions by companies and others who are required by law to file forms with the SEC.

EGAR’s primary purpose is to increase the efficiency and fairness of the securities market by accelerating the receipt, acceptance, dissemination and analysis of time-sensitive corporate information filed with the SEC. A secondary purpose of EDGAR is to provide transparency in the marketplace by making documents that have been filed quickly available to investors over the Internet.

For Important Information About EDGAR please see https://www.sec.gov/edgar/aboutedgar.htm

Thank you for your time I hope this helps any members on this form to understand "The Dome-of-Silence" (or those familiar with Get Smart episode 1 "Cone of Silence") that SP is held to.

b1naryn1ghtmar3, Welcome to the Forum.

When we were first planning our farm we did a lot of research on power distribution and Heat / Cooling and our happy to share our findings with you.

Power Distribution:
22 units @ 3,600watts = approx 79,200 (+/- 10% to 12% leakage) watts just for SP-35's (H-$7.92, D-$190.08, W-$1,330.56, M-$5,702.40, A-$69,379.20 US @ .10 ($/kWh)
(Cooling not including in this calculation)

The "Heavy Power" standard for the United States is 3-phase voltages of 208, 220, 230, 440, 460 480
79 Kw Line to Line voltage for 220 with power factor of 1 is approx. 207.321 Amps
79 Kw Line to Line voltage for 480 with power factor of 1 is approx. 95.0222 Amps
 (Note: Calculation assistance http://www.rapidtables.com/calc/electric/KW_to_Amp_Calculator.htm)


PDU RESEARCH: We narrowed it down to 3 companies Raritan.com, Tripplite.com and APC.com (now a Schneider Electric Company).  We went with Raritan PX family of intelligent iPDUs for the individual outlet switching, monitoring and high amperage per unit. They are a little expensive but we have found that they more than paid for themselves with the expanded flexibility.

HUBS: as for your question on Hubs; I would not use a "HUB" it is a broadcast device all communication to all ports.  A "Switch" allows communication to be directed on a port-by-port basis.  The Sp-35's use 10/100mbs Ethernet so make sure so make sure your switch can handle 10/100/1000.  We went with http://www.BROCADE.com switches and routers (note: we had them already and they are very expensive but I would buy them again if we were starting this project from scratch). 

COOLING: We have found setting COLD/HOT isle worked best for us.  Cold Isle is referencing "Conditioned Air" in the front of SP-35 (estimate approx. 93dB) and Hot Isle is the exhaust heat out of the back of the unit (estimate approx 82 dB).  We Opted for Air & Evap. Cooling in Louisville, Ky. (Mid-West of the US).  Another option working into the Fall/Winter is to Evacuate the Hot Side back into the office (People Conditioned Air) or just Out-Side to the environment).  We opted for "Containment or Container" based Cold/Hot instead of Data Center philosophy of cool the hot air and blow it up (Loop or Circle or Air).

INTERNET BANDWIDTH: We have a 100/100mb Fiber Internet Connection and the "Server Farm" is only a small fraction of the UP/Down Load connection, most internet traffic is "East/West" (Server to Server), "North" is Internet or Crypto Authentication and "South" is to the secure servers.  With 22 Sp-35's a Low bandwidth connection ranging of 10/1, 15/2, 35/5 or 50/5 connect will be more than plenty.  I never scrimp on "Bandwidth up or down", I can always use more.  [/li][/list]

NOTE: There are a number of Tools out in the Free or Open Source pool that will help you SSH, Monitor, Control or Adjust the Sp-35's in your stable.

NOTE 2: Our next generation is/will be Containerized @ 1.2Mw - 1.4Mw each and placed approx 80'-100' underground for cooling.  Heat evacuation is one of our biggest issues/concerns.

Thank You Roadstress,

I did see and appreciated the humor of the bubble bursting ( as I am invested in this growth like most of us in this forum).   But is SP-Tech the proper forum or could the post be better placed and possibly reach a wider or more receptive audience.

I am not trying to stir the pot or start a on-line battle.  I am just trying to keep this forum focused on it's original purpose, to provide support and information related to Spondoolies-Tech.

Thank you for your time in advance,

  /s/ TuffToad

Unacceptable,

Thank you for the post, I fail to see the relevance to Spondoolies-Tech forum or the previous post that you replied.

Your link might be better suited to another forum.

 Thank You for your time,

Bitcoin mining equipment Bitmain Antminer S3 w/power supply ready togo - (West Chester)
$190


I have a Bitmain Antminer S3 with a 750 watt power supply that you have to buy separately but I already have this included all as a package deal. The Antminer s3 alone online is 140, power supply would be 70, and shiping for all the equipment would be pricy. If you want to start mining Bitcoin or any sha256 based crypto-currency. Start stacking up your online bank today with this bitcoin crypto-currency miner. Just call or text me anytime to pick up. Ask about my other bitcoin mining equipment.
